83866600 divided by 607 
We want to figure out the number of times 83866600 can be divided by 607.

Advancing to step 1:
The number 607 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 607

Going ahead to step 2:
607 goes into 83 0 times with a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Grab the next digit (8) from the dividend, add it to 83, then carry on: 838 / 607

Going ahead to step 3:
When dividing 838 by 607, we get 1 with a remainder of 231.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 607 away from 838, we end up with 231.
Fetch the next digit (6) from the dividend, attach it to 231 and continue: 2316 / 607

Let's proceed to step 4:
The number 607 fits into 2316 3 times, leaving a remainder of 495.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 495 after subtracting 1821 from 2316.
Grab the next digit (6) from the dividend, add it to 495, then carry on: 4956 / 607

Moving on to step 5:
607 goes into 4956 8 times with a remainder of 100.
Use 8 as the next digit of our solution. 
Result so far: 138.0
If we take 4856 away from 4956, we end up with 100.
Include the next digit (6) from the dividend after 100, then repeat: 1006 / 607

Advancing to step 6:
607 goes into 1006 1 times with a remainder of 399.
Write down 1 as next digit of the result. 
Result so far: 1381.0
If we subtract 607 from 1006, we get 399.
Fetch the next digit (0) from the dividend, attach it to 399 and continue: 3990 / 607

Let's proceed to step 7:
If we divide 3990 by 607, we get 6 and a remainder of 348.
The next digit of our result is 6. 
Result so far: 13816.0
If we subtract 3642 from 3990, we get 348.
Grab the next digit (0) from the dividend, add it to 348, then carry on: 3480 / 607

Moving on to step 8:
607 goes into 3480 5 times with a remainder of 445.
Write down 5 as next digit of the result. 
Result so far: 138165.0
The remainder is 445 after subtracting 3035 from 3480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Step 9:
607 can be fit into 4450 7 times, resulting in a remainder of 201.
Use 7 as the next digit of our solution. 
Result so far: 138165.7
If we take 4249 away from 4450, we end up with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Moving on to step 10:
If we divide 2010 by 607, we get 3 and a remainder of 189.
The next digit of our result is 3. 
Result so far: 138165.73
If we subtract 1821 from 2010, we get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Advancing to step 11:
607 can be fit into 1890 3 times, resulting in a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 138165.733
If we subtract 1821 from 1890, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

The final result is 138165.733 with a remainder of 0.0069.
